Where's the connection between DNS Cache and cookies? Two very different things. If you want to selectively delete or save cookies, download the free program CCleaner. It allows you to see what cookies are stored, select which to keep, and delete the rest. Also does a good job of cleaning temporary internet files from IE and other browsers and e-mail clients.
